[Health services research in acute pain medicine : Where do we come from in Germany?].

Background: Up to the early 2000s the need for optimization in the treatment of acute pain in hospitals was highlighted. Only a few successes were achieved in the optimization process. As the acute pain care in Germany remained persistently unsatisfactory, the first health services research projects in pain medicine were initiated. These were intended to achieve improvements in patient care.

Aim: To illustrate the beginnings of health services research in the field of pain medicine in Germany the research projects "Pain-free hospital" and "Action alliance pain-free City of Münster" as well as the certification initiative Certkom are described.

Material And Methods: An analysis of the current state of pain care for patients and interdisciplinary pain management, the derivation of optimization measures, their implementation and subsequent evaluation were carried out in all the projects presented in the sense of a complex intervention.

Results: All the projects could achieve improvements in patient care through a systematic survey of the current situation, targeted planning and the introduction of optimization measures. Corresponding evaluations could demonstrate these results.

Conclusion: The systematic approach in the projects with the collation of scientific data in real-life care has achieved optimization in acute pain management. The foundations were laid for further healthcare research in pain treatment in Germany; however, the projects also revealed limitations in the inclusion of vulnerable patient groups.
